Sebastian Ottlik f62cafd4c8 target-arm: fix ARMv7M stack alignment on reset ... When the initial SP is loaded from the vector table on ARMv7M systems the two least significant bits are ignored as the stack is always aligned at a four byte boundary (see ARM DDI 0403C, B1.4.1 and B1.5.5). So far QEMU did not ignore these bits leading to a stack alignment inconsitent with real hardware for binaries that rely on this behaviour. This patch fixes this issue by masking the two least significant bits when loading the SP.
